CU LTIVATOR.

SPECIFICATION forming part f Letters Patent No. 476,834, dated June 14,1892.

Application filed March 28, 1892. Serial No. 426,733. (No model.)

T0 all whom t may concern,.-

Beit known that I, JAMES D. SIMMONS, a citi-1 zen of the United States,residing at Hagerstown, in the county of Vashington and StateofMaryland, have invented certain new and useful Improvements inCultivators; and I do hereby declare the following to be a full, clear,

and exact description of the invention, such as lwill enable othersskilled in the art to which 1t appertains to malte and use the same.

This invention has relation to improvements in cilltivators; and itconsists in the novel construction, combination, and arrangement of thesame, all as will be hereinafter more fully described.

rlhe annexed drawings, to which reference is made, fully illustrate myinvention, in which- Figure l represents a top or plan view of myimproved cultivator. Fig. 2 is a vertical sectional view of the same.Fig. 3 is a detached sectional view7 and Fig. 4 isa perspective View, ofthe lever and knee-joint bar.

Referring by letter to the accompanying drawings, A designates the frameof the cultivator, consisting of the front cross-bar a, rear cross-barb, and short arms c, which conneet the front and rear bar to oneanother. The tongue Bis connected to the frame in the usual manner andhas side braces d d, con` necting the front bar of the frame with thetongue.

The doubletree e ofthe cultivator is not pivoted in the usual manner tothe tongue, but passes through hangers ff, secured to and on each sideof the tongue. This doubletree has its forward and backward slidingmovement between the horizontal bar g of each hanger and the under sideof the tongue. Apin 7L is passed through the doubletree on the outsideof each hanger to prevent lateral movement of said doubletree. To thecentral portion of thisdoublctree, as at d', is secured one end of apair of chains 'i i', the opposite ends of which are secured to the endcross-bars of the main frame, as at h.

C represents the spring cult-ivator-teeth, the forward ends of which arepivoted to the front cross-bar and on the top of the same, and beingpivoted, as shown, to the top of the front crossbar the draft is lessand draws more in a straight line when the machine is moved forward, andsaid teeth are supported by a short "barj, which is arranged directlyabove the rear The upper cross-bars cross-bar of the frame. njarearranged in sections. Each section, `with its cultivator teeth, isindependent of the other, said bars being notched at c to receive thehorizontal portion of the tooth, and above .the same is a spring-holdingplate for each of said teeth, consisting of a top plate 7.3, which isxed to the cross-bar j by bolts Z Z, and a movable plate m, that slidesvertically upon said bolts. Interposed between these plates is a springn, that bears upon the movable plate and holds the latter down upon thespring-teeth. Pivoted at its front end to the frame is a lever D. Eachsection of the teeth is provided with one of these levers. The same isbolted to the upper cross-bar, as at d', and is slotted at o in rear ofsaid bar. Vithin this slot is pivoted one end ofajointed bar E, the endp of which extends somewhat above the lever D to form a handle, for apurpose hereinafter explained. This bar Eis hinged at q, forming aknee-joint, while the endi1 is pivoted at s to the rearcross-bar of theframe, and in raising the teeth by sections or a single section at atime the jointed bar serves to hold the section in a raised position,thus clearing the teeth from the ground. The extended end p of theknee-bar serves as a handle to straighten said bar for supporting thesection.

F designates the transporting-wheels, which are arranged to revolve on atransverse bar t, that extends from one side of the frame to the otherside and is secured to said frame. These wheels are arranged somewhatinwardly from the outside of the machine and between each outsidetooth-section and the adjacent section. The same carry the weight of theframe and teeth as well as the drivers seat G, which is mounted on themain frame. It will thus be observed that in operation, when any of theteeth come in contact with an obstruction the cross-plate above saidtooth, with its spring thereon, gives and saves the tooth from injury,and should a solid obstruction be encountered the entire springtoothsection will rise and overcome the same. When itis only desired to useone or more sections, the re- IOO mailling* section or sections can bereadily raised from the ground by the lever and held elevated by theknee-jointed bar. It will be further seen that by the arrangement of thedoubletree within the hangers the same has a forward and backwardmovement, and by the novel connection ofthe doubletree, by the chains,to the frame the draft on the team is equalized. Should one horse drawmore than the other horse, the strain Will be upon the chain on theopposite side of the tongue, and the pins in said doubletree serve tokeep the latter in position. Thus it will be readily observed that Iconstruct a cultivator, whereby a few teeth may be operated at a timeand that the draft by the team through the 1nedium of the chains iseqnalized, and by pivoting the end of the teeth to the upper portion ofthe front cross-bar there is less resistance and strain, an d the deviceherein described is durable, easily operated, and at the same time cheapto manufacture.

Having thus described my invention, what I claimas new, and desire tosecure by Letters Patent, is-

In a cnltivator, the combination, with the frame havingtransporting-Wheels, of the teeth pivoted on top of the front cross-bar,the movable crossbar beneath said teeth, the plates arranged above theteeth and provided with the spring, the hand-levers pivoted at theirforward ends to the frame and secured about their center to the movableupper crossbars and provided with the slot, and the jointed bars pivotedto the rearcross-barof the frame and hinged, as shown, the upper endpassing through and pivoted in the slot of the lever, the extended endof said bar serving as a handle, substantially as described.

In testimonywhereof I affix my signature in presence of two witnesses.

JAMES D. SIMMONS.
